For the functions you describe, some central server is needed that knows 
which Nebraska-servers are online and want to give access to others.

Chat-programs tell to a chat-server that they want to take part in 
discussions. These servers manage the list of active participants (and of 
course discussion channels). This list-managing function is not built into 
Nebraska. 

One solution would be to write a program for this function and install it 
on a central server. Nebraska-servers should tell 'central' that they are 
active. Clients could contact 'central' 

As IRC processing is already available in Squeak, I think it is possible to 
let Nebraska-servers communicate by an IRC channel. That way, N-servers 
could find out which are on line. After IRC is used to find out with whom 
to communicate, further communication could be in the normal way.

Anyhow, it is not possible to find a solution without some programming. 

When 'public' is invited to participate in visual group working, 'noisy' 
activity can become much more troublesome than in IRC. In IRC, everybody 
can read the history because it is local. It is possible not to read 
disturbing messages. With a visual chat, the drawingboard is the history. 
If somebody disturbs it,  both the result as the history are gone. So more 
thinking about granting accessrights is necessary.
